Accepted Answer

Moderate acute intoxication with ethyl alcohol produces dilated pupils,not constricted pupils.The other choices are all characteristic of ethyl alcohol intoxication.

Question 2

Nitrous oxide abuse

Accepted Answer

Chronic use can cause mental dysfunction and infertility.Nitrous oxide use does not cause physical dependence.Abuse is primarily by dental personnel.Nitrous oxide causes myeloneuropathy,not myelocytosis.

Question 3

The potential for abuse of a drug is greatly increased by all of the following factors except which one?

Accepted Answer

The abuse potential of a drug is increased if it has a quick onset of action.The duration of action of the drug is less important,and a longer duration often reduces the opportunity for a subsequent "rush" and the cycle of repetitive use.Potency,cost,and ease of access are all incentives to maintain a drug habit.

Question 4

Physical dependence

Accepted Answer

Physical dependence refers to the altered physiologic state that results from constantly increasing drug concentrations.It is established by withdrawal syndrome,a combination of many drug-specific symptoms that occur on abrupt discontinuation of drug administration.Psychologic dependence is a state of mind in which a person believes that he or she is unable to maintain optimal performance without having taken a drug.

Question 5

Which of the following statements is true regarding addiction,habituation,and dependence?

Accepted Answer

Cross-tolerance may be either partial or complete and is determined more by the pharmacologic effect of the drug than by its chemical structure.When comparing drugs of the same group,the time required to produce physical dependence is shortest with a rapidly metabolized drug and longest with a slowly metabolized drug.The shorter the half-life is,the quicker the withdrawal will be.If a person is addicted to heroin,an opioid,then other opioids,such as morphine,can prevent withdrawal.However,a barbiturate cannot be substituted for an opioid,and vice versa.

Question 6

Disulfiram is an agent used in the treatment of

Accepted Answer

Disulfiram (Antabuse)hinders alcohol metabolism and leads to a rise in acetaldehyde in drinkers.This property acts as a deterrent to drinking and as an incentive to stay sober.Disulfiram is not effective in any of the other conditions.

Question 7

Advanced periodontal disease,jaundice,and palmar erythema are signs of

Accepted Answer

These three signs point to alcoholic's poor oral hygiene,liver damage,and peripheral vasodilation.Smokeless tobacco use would cause periodontal disease but not the other symptoms.Wernicke encephalopathy would cause amnesia.Chronic nitrous oxide use does not produce these signs.

Question 8

Which of the following statements is true of alcohol use disorder?

Accepted Answer

Genetic testing may someday be able to identify at-risk children and target this population for intense educational and social intervention for prevention.A genetic link for alcohol use disorder has been found;children of alcoholics are at much greater risk for becoming alcoholics.Inpatient treatment does not give the alcoholic any experience in recovery in the "real world." Disulfiram (Antabuse)rather than penicillin is associated with a deterrent reaction.Certain other drugs that produce the disulfiram-like reaction (e.g. ,metronidazole)may cause a minor version of these symptoms with alcohol consumption.

Question 9

Which of the following drugs may be used to reduce alcohol craving?

Accepted Answer

Naltrexone (ReVia)is an oral opioid antagonist.Because naltrexone is partially effective in decreasing craving from alcohol,the logical conclusion is that alcohol stimulates some of the opioid receptors.Naltrexone is used to reduce alcohol craving.

Question 10

Enabling is an inappropriate behavior that requires family therapy because it involves the actions that family or friends take to supply the addict with the drug.

Accepted Answer

Enabling is an inappropriate coping mechanism that requires family therapy.Enabling is the behavior of family or friends who associate with the addict that results in continued substance abuse.It may have nothing to do with providing the addict with the drug.Thus,because this dysfunctional behavior is counterproductive,the first statement is true.However,enabling is much more subtle than actually supplying the drug.

Question 11

Which drug is associated with a deficiency of coagulation factors II,VII,IX,and X after chronic abuse?

Accepted Answer

Because of ethyl alcohol-induced hepatic failure,the liver is able to store less vitamin K,which is required for the synthesis of coagulation factors II,VII,IX,and X.The other agents do not produce a deficiency in these coagulation factors.

Question 12

Agents capable of changing behavior or inducing a psychosis-like reaction are termed

Accepted Answer

The statement is the definition of psychoactive,which includes drugs with therapeutic value and those without therapeutic value.Psychedelic drugs are the subset of psychoactive drugs that have no therapeutic value.Hallucinogenic drugs may produce hallucinations and psychotic-like behavior and are categorized with psychedelic drugs.Psychotomimetic drugs produce effects that mimic psychoses;they exclude several psychoactive drugs that do not mimic psychoses.

Question 13

At which stage of ethyl alcohol withdrawal are hallucinations most prevalent?

Accepted Answer

Stage 2 withdrawal includes hallucinations,paranoid behavior,and amnesia.Although overlap in symptoms can be considerable,hallucinations generally occur after stage 1 and before stage 3.

Question 14

Abuse of _____ is the number one public health problem in the United States.

Accepted Answer

Question 15

All of the following statements are descriptive of psychologic dependence except which one?

Accepted Answer

Even though some highly abused drugs have only psychologic dependence,the "need" to use these drugs can be as strong or stronger than drugs with a physical dependence.All other statements are characteristic of psychologic dependence.

Question 16

The recurrent use of alcohol and/or drugs causing clinically and functionally significant impairment is called

Accepted Answer

According to The Diagnostic and Statistical Manual of Mental Disorders,Fifth Edition (DSM-5)a diagnosis of substance use disorder is based on evidence of impaired control,social impairment,risky use,and pharmacological criteria.Substance Use Disorders are defined as mild,moderate,or severe that is determined by the number of criteria that the person demonstrates.Enabling is the behavior of family or friends that allow the drug-dependent person to continue his or her habit.The definition applies to more than psychologic dependence.Tolerance often occurs before or during but is not equivalent to drug dependence.Abstinence syndrome or withdrawal is a set of physical and psychologic symptoms that occurs when a drug-dependent person stops taking a drug.One symptom might be the compulsion to take the drug.

Question 17

Chronic alcohol use increases the risk of cancer of the mouth,pharynx,larynx,esophagus,and liver,which may occur with tobacco use in a(n)_____ effect.

Accepted Answer

The liver can be affected with alcoholic hepatitis and amnestic syndrome (Wernicke-Korsakoff)syndrome,and peripheral neuropathy can occur.Chronic alcohol use increases the risk of cancer of the mouth,pharynx,larynx,esophagus,and liver,which may occur with tobacco use to make the risk higher than with alcohol alone.

Accepted Answer

In terminal patients,this tolerance requires ever-increasing doses of opioids even if the pain remains constant.Tolerance is characterized by the need to increase the dose continually to achieve a desired effect or providing the same dose that produces a diminishing effect.

Question 20

How many Americans who drink have alcohol use disorder?

Accepted Answer

In 2010,alcohol misuse costs the United States 249 billion dollars.Three quarters of the total cost of alcohol misuse are related to binge drinking.Data from the National Survey on Drug Use and Health showed that 52.4% of all Americans age 12 and older reported drinking alcohol.Most drink in moderation,however,over 17 million Americans who drink alcohol have alcohol use disorder.
